The Myers-Briggs Type Indicator (MBTI) is becoming popular among Gen Z. It is a personality test that categorizes people into 16 personality types. These types are represented by different letters: E (extraversion) or I (introversion), S (sensing) or N (intuition), F (feeling) or T (thinking), P (perceiving) or J (judging). 

The way zodiac signs and MBTI embody personality tags in our society now indeed constitutes the Barnum Effect -– when people think that personality descriptions are uniquely relevant to them, despite its universality --- but how convincing is that?
